FRANK I. BEMY AND BENJAMIN I BEMY, OF ANDERSON, INDIANA, ASSIGNORS TOREHY ELECTRIC COMPANYQOF ANDERSON, INDIANA, A CORPORATION.

MAGNETO-ELECTRIC GENERATOR.

To all whom it'may concern:

Be it known that We, FRANK I. REMY and BENJAMIN P. REMY, of Anderson,county of Madison, and State of Indiana, have invented-a certain new anduseful Magneto-Electric,"g fienerator; and we do herebydeclare that'thefollowing is a full,

The object of this invention is to both improve the construction ofmagnetos for the purpose of simplifying the same and reduclng the-costof makin and assembling, and to improve the operation and generativepower thereof. 1

The chief feature of the invention consists 'in providing pole pieces onop osite sides of advantage of this feature of the construction is thatit increases thepower and effectiveness of the device, as it enables thebore of the field to be of greater diameter than the width. of themagnets, instead of materially less when the magnets extend down to thelower-edge of the pole pieces, and yet the function and influence of themagnets are notfdiminished.

Another'feature of the invention consists in clamping the strap forsecurely holding horseshoe shaped magnets down in place in connectionwith the casing or frame of the magneto.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims y withthe pole pieces 11 constituting the sides and with a top 12 upon thepole pieces, said top' and bottom being secured to the pole pieces byscrews or other means. Hence in this magneto the pole pieces constitutethe two sides of what may be considered the casing. The ends'13 of thecasing are se- Specification of Letters Patent Application filed March25, 1909.

cured to the other parts thereof in any suitable manner. In ,the endsthe armature shaft 14. is centrally mounted and carries .of thepolepieces and rest upon t e shoulders 19. The pole pieces arelongitudinally recessed along the upper outer edges for the lower endsof the outer magnets, so that the outer surfaces of the magnets and polepieces will be flush, but the magnets do not extend down to the middleof the pole pieces. The inner set of magnets rests upon the top of thepole pieces and a ainst the outer edges of the top 12 of tie casing.Therefore, the magnets tend to hold the pole pieces and other parts inplace.

In this construction itis observed that the diameter of the field orspace between the pole pieces is materially greater than if the polepieces were enveloped by the ma nets, and in fact, the diameter of thefielc is greater than the space between the magnets, and the power ofthedevice is proportionately increased, and this result is accomplishedwithoutdiminishing the influence of the magnets upon the field. Thisconstruction also permits the use of a relatively large wound armature.

The magnets 18 are held firmly in position by a strap 20 that )assesover thetops of the magnets longitudinally of the magneto and diagonallyunder the magnets to a clamping screw 21, which screws into a boss inthe top of the casing. or frame12. By tightening the screw 21 the clampscan be drawn down tightly on the magnets, so that they will be firmlyheld in position during rough usage, as for example, in automobiles.

\Vhat we claim as our invention and sire to secure by Letters. Patentis:

1. A magneto electric generator includ-' ing and holding said strap downtightly in place. i

-2. A magneto eleetric generator including a case or frame, horseshoeshaped magnets 5 mounted in connection with said casing or fraune, astrap extending over the tops of said magnets 'with the ends thereofextending downwardly, and means mounted in connection with the top ofthe frame of the 10 casing with which the-endsof said strap I areconnected for drawing and hol ling said strap down tightly in place. InWitness whereof, We have hereunto afi ixed our signatures in thepresence of the witnesses herein named.
